TestML - Data Driven Testing for All Modern Programming Languages

by Ingy dot Net

In 2004 I created the Test::Base data driven testing module for CPAN. It
became popular with several prolific CPAN authors like MIYAGAWA and became
the main testing framework for companies like Socialtext and OpenResty, In
2010 I decided to "Acmeize" it and I made TestML with the intent of making
it work in all programming languages. I got it going in Perl5/CPAN and a
couple other languages. In 2017 OpenResty paid me to write a new version of
the language in their proprietary ecosystem, and the resulting idea was
really much better. They allowed me to take the new ideas to Open Source
and in 2018 I have the new great TestML language. It is currently working
in 8 languages (Bash, CoffeeScript, Go, JavaScript, Perl 5, Perl 6, Python
2 and Python 3) and easy to port. Other ports are under way including C++.
The official YAML test suite is written in TestML!

In this talk I will:

Introduce you to the TestML language
(it's so simple, most programs are a single line!)

Show how TestML works well with any language's existing test frameworks

Show how to use in Perl 5 and 6 and others

Show how the language is compiled to Lingy (a JSON based Lisp)

Show how to port TestML to a new programming language or test framework
